Gemstones You'll Encounter
Brazil is one of the world's most important sources of colored gemstones. On this expedition, you'll visit the origins of some of the most coveted gems in the industry.
Paraíba Tourmaline
Parelhas, Rio Grande do Norte
First discovered in 1987, Brazilian Paraíba tourmalines are among the rarest and most valuable gems in the world — known for their extraordinary neon blue and green hues caused by copper and manganese inclusions.
Imperial Topaz
Ouro Preto, Minas Gerais
Ouro Preto is the only known source of true Imperial Topaz in shades of golden orange to reddish-orange with pink undertones — a gem historically reserved for royalty and among Brazil's most prized treasures.
Brazilian Emerald
Belmont Mine, Minas Gerais
The Belmont Mine is one of World's premier privately operated emerald mines, producing gems celebrated for their vibrant bluish-green color and relatively low inclusion levels compared to other origins.
Tourmaline
Governador Valadares, Minas Gerais
Governador Valadares is World's most important tourmaline trading hub, producing a spectacular array of colors — from the coveted Indicolite blues to bi-color specimens — traded globally from this city.
